No there are a couple of good ones. like Shawshank and Green Mile. but the majority.... like Sleepwalkers... and Tommyknockers... and Langoliers... and The Dark Half...

Shawshank is one of my top rated books/movies. Back to books that I think would make a good movie, River God by Wilbur Smith. Could not get into many of his books, but I think that could be an epic movie. The follow up The 7th Scroll could also do a movie justice if done right.

Update (06/02/15): Since publishing this piece, reports leaked that Sony Pictures is eying Nikolaj Arcel, director of the Oscar-nominated A Royal Affair and writer of the original Girl with the Dragon Tattoo film, to take the Dark Tower reins.

I do have a very bad experience with Books becoming movies! A VERY good example is the Hobbit movie series....
This Thread should be named Books that should STAY books and NOT become movies! Just to keep that vision you have in your mind of your favorite books untarnished by a movie.
